Aluminium Conductors


Aluminium Conductors Steel Reinforced (ACSR)
ACSR conductors consist of a solid or stranded steel core surrounded by strands of aluminium (E.C.Grade). ACSR conductors are available in a wide range of steel, containing carbon from 0.5% to 0.85%. The higher strength ACSR conductors are used for river crossings, overhead ground wires, installation involving extra long spans etc. Against any given resistance of conductor,ACSR may be manufactured for having a wide range of tensile strength as per the requirement.

The principle advantage of these conductors are high tensile strength so that they are used for longer spans with less supports. Due to greater diameter of ACSR conductors a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage overhead lines.

AAC conductors are made out of Hard drawn EC Grade(min 61% IACS) Aluminium wires stranded in successive layers in opposite direction to form the Aluminium stranded AAC Conductor up to 61 wires.

Key Benefits
All aluminium bare conductors are used for aerial distribution lines having relatively short spans, aerial feeder and bus bars of substations.

All Aluminium Alloy Conductors (AAAC)
This conductors is made from aluminium - magnesium - silicon alloy of high electrical conductivity containing enough magnesium silicide to give it better mechanical properties after treatment. These conductors are generally made out of aluminium alloy 6201. AAAc CONDUCTOR has a better corrosion resistance and better strength to weight ratio and improved electrical conductivity than ACSR CONDUCTORS on equal diameterbasis.

All Aluminium Alloy Conductors (AAAC)
AAC conductors is made from aluminium - magnesium - silicon alloy of high electrical conductivity containing magnesium (0.6-0.9%)& silicon (0.5-0.9%) to give it better mechanical properties after treatment. AAC conductors are generally made out of aluminium alloy 6201 (minimum conductivity is 54%). AAAc CONDUCTOR has a better corrosion resistance and better strength to weigh tratio and improved electrical conductivity than ACSR CONDUCTORS on equal diameter basis.

Key Benefits
  • High tensile strengths as compared to AAc conductors.
  • Higher conductivity as compared to ACSR conductors.
  • Better corrosion resistance than ACSR conductor.
